âDermatosparaxis EDS â Dermatosparaxis is a rare form of EDS (MIM #225410) that is inherited in an autosomal recessive fashion. It is due to mutations in the ADAMTS2 gene, which result in deficiency of procollagen I N-terminal peptidase [20].
Distribution and habitat. Rheas are from South America only and are limited within the continent to Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay. They are grassland birds and both species prefer open land. The greater rheas live in open grasslands, pampas, and chaco woodlands.
The plains near the Straits of Magellan are inhabited by one species of Rhea (American ostrich), and northward the plains of La Plata by another species of the same genus; and not by a true ostrich or emeu, like those found in Africa and Australia under the same latitude.
